Trouble
Possible Reason
Solution
After power on, motor can’t work,
no sound is emitted
The connections between
battery pack and ESC are not
correct
Check the power connections
Replace the connectors
After power on, motor can’t work,
but emits “beep-beep-, beep-beep-”
alert tone. (Every “beep-beep-” has
a time interval of 1 second )
Input voltage is abnormal, too
high or too low.
Check the voltage of the battery pack
After power on, motor can’t work,
but emits “beep-, beep-, beep-”
alert tone. (Every “beep-” has a
time interval of about 2 seconds)
Throttle signal is abnormal
Check the transmitter and the receiver
Check the wire of the throttle channel
The motor runs in the opposite
direction
The wire connections between
ESC and the motor need to be
changed
Swap any two wire connections
between the ESC and the motor.
The throttle signal is lost
Check the transmitter and the receiver
Check the wire of the throttle channel
The ESC has entered the Low
Voltage Protection Mode
Replace the battery pack
The motor stops running while in
working state
The ESC is over heat
Restart the RC boat after a few minutes
Program The ESC

2. Programmable
Values
a)
Running Mode:
With
“Forward Only” mode, the boat can go forward, but cannot go backward, this mode is
suitable for competition; “Forward/Reverse” mode provides backward function, which is suitable for training.
Note: “Forward/Reverse with Brake” mode uses “Double-Click” method to make the boat go backward
.
When you move the throttle stick from forward zone to backward zone for the first time, the ESC begins to brake the
motor, the motor speeds down but it is still running, not completely stopped, so the backward action is NOT happened
now. When the throttle stick is moved to the backward zone again (The 2
nd
“click”), if the motor speed is slowed down
to zero (i.e. stopped), the backward action will be occurred. The “Double-Click” method can prevent mistakenly
reverse when the brake function is frequently used in steering.
In the process of braking or reverse, if the throttle stick is moved to forward zone, the motor will regain forward
running at once.
b)
Low Voltage Cut-Off:
The function is mainly to prevent the lithium battery pack from over discharging. When
using lithium battery pack, please set the suitable value for low-voltage protection as your like.
The ESC monitors the
battery’s voltage at any time, if the voltage is lower than the threshold, the output power will be cut off.
c)
Brake Function:
When this function is activated, the motor can be stopped in a shorter time.
d)
Timing:
There are many differences among structures and parameters of different brushless motors, so a fixed
timing ESC is difficult to compatible with all brushless motors. It is necessary to make the timing value programmable.
Please select the most suitable timing value according to the motor you are just using. Generally, higher timing value
brings out higher power output, but the whole efficiency of the system will be slightly lower down.
3. Reset All Items To Default Values
At any time when the throttle is located in neutral zone (except in the throttle calibration or parameters program
process), hold the “SET” key for over 3 seconds, the red LED and green LED will flash at the same time, means each
programmable item has be reset to its default value.
Please calibrate the throttle range again after resetting
.
